Decommissioning / servicing / cleaning
When performing any cleaning or servicing work on the ventilation unit, always fully isolate
the ventilation unit from mains! Rotating components may otherwise pose a hazard in case
of accidental switch-on.
All fans or rotating parts must be stationary before opening the door. The underpressure in the unit may
draw in loose parts, possibly damaging the fan or posing a threat to life and limb.
Other existing plant components and system subassemblies such as geothermal heat exchanger, pre-
and re-heater battery, acoustic dampening etc. must be serviced and cleaned according to the
regulations and instructions.
If possible, use a vacuum cleaner to remove dirt and dust. Applying force or using compressed air for
cleaning may damage components and surfaces.
Never use aggressive or solvent-containing cleaning agents.
The electrical components must not be exposed to moisture or wet conditions.
The
Safety notes in Section 2.2
, especially
Section 2.2.3
